MECHANISM Rudolph I. Schonitaer, Shaker- Height, Ohio Application September 14, 1938, Serial No. 229,800 14 Claims. (Cl. sac-21s) This invention relates to door holding and door 3 control mechanism, whereby a hinged door, such as an automobile door, for example,'may be more or less rigidly or unyieldably held against move- 5 ment in the general direction of its hinge axis throw-out control or a combined latch and throwout control, all as will hereinafter. more fully appear. j I

In my prior United States patent for a Door support, Patent No. 1,963,475, two separate and independent means are disclosed for rigidly holding a hinged door, such as an automobile door, against movementin the general direction of its hinge axis when such door is in closed position within its surrounding frame, but neither of such door holding means is combined or cooperatively related with any control means for said door, including the lock or latch control means therefor. .In my prior United States patent for Door control mechanism, Patent No. 2,094,413,,mecha nism is disclosed for suitably controlling a hinged door, such as an automobile door, for example, the

door control there disclosed being a latch control door. i

The present invention, therefore, has'for its general object the provision of mechanism which comprises combined or cooperatively related door holding parts and door controlling parts, the com- I blnation or cooperative relation of such parts being of such character that the more or less rigid.

or unyieldable holding of a door against movement'in the general direction of its hinge axis when such door is in closed position and the control of such door are efiected in a particularly novel and exceedingly practical manner.

A further object of the present invention is the provision of door holding and door control mechanism for a hinged automobile door orthe like,

of providing for such door dove-tails" or other f, separate devices such as are now utilized for doorholding purposes.

A further object of the present invention is the provision of door holding and door control mechanism for a hinged automobile door or the like, said mechanism being of such character that the door with which it is used has a single predeter- 5 mined closed position, irrespective of the presence or absence of the yieldable door bumpers which are now provided for automobile doors. With such mechanism, therefore, the use of such door bumpers isentirely optional.

A further object of the present invention is the provision of door holding and door control mechanism which is of extremely simple and inexpensive construction; which comprises readily and conveniently assembled parts of strong and sturdy character; which provides for the necessary initial adjustment of parts to enable saidv mechanism to be used with any door, notwithstanding normal variations in the mounting thereof, etc; and which mechanism does not thereof, reference being bad to the accompanying drawings in which such embodiments are illustrated in connection with a hinged automobile door, said door and its surrounding frame being of standard form.

In said drawings, in which Figs. 1 to 6 inclusive illustrate one form of mechanismembodying the present invention, Fig. l is an elevation of a side portion of an automobile body door frame to which are secured certain parts of such mecha nism; Fig. 2 is an elevation of a portion of a side edge wall of a hinged automobile door to which are secured other parts of such mechanismyFig. 3 is a vertical longitudinal sectional view, on the line 1-3, Fig. 4, through such portions of said auto mobile body door frame and said automobile door, the door being latched in closed position and being rigidly or unyieldably held against up and down movement within its frame; Fig. 4 is a vertical cross-sectional view of such portions, on the line 4-4, Fig. 3; Fig. 5 is a vertical cross-sectional view through a portion of the automobile door, the parts of the mechanism there shown being in the positions which they occupy when the door is in its closed position; Fig. 6 is a view similar to Fig. 5, but showing such parts in the positions which they occupy when the door is open; Figs. 7 and 8 are views illustrating another form of mechanism embodying the present invention, Fig. 7 being a view on the line 1-1, Fig. 8, and corresponding in part to Fig. 3, and Fig. 8 being a view on the line 8-B, Fig. 7, and corresponding in part to Fig. 4; Figs. 9 and 10 are views illus- 5 require any attention during its exceptionally 15 is automatically trating another form of mechanism embodying the present invention, Fig. 9 being if view corresponding in part to r for example, such mechanisms are Figs. 4 and 8, and Fig. 10 being a view similar to Fig. 9, with the pivoted door control member shown by dot-dash lines in operated position; Figs. 11 and 12 are views corresponding respectively to Figs. 9 and 10 and showing another form of mechanism embodying the present invention; and Figs. 13 and 14 are views corresponding respectively to Figs. 9 and 10 and showing another form of mechanism embodying the present invention.

Before the present invention is described in detail, it is to be understood that such invention is not limited to the details of construction and/ or the specific arrangements of parts herein illustrated and/or described, as the invention obviously may take other forms. It also is to be understood that the phraseology or terminology herein employed is for the purpose of description and not of limitation, there being no intention and no desire to limit the present invention, as herein disclosed and as defined in the appended claims, beyond the requirements of the prior art.

Although door holding and door control mechanisms embodying the present invention are applicable for use with the hinged doors of various structures, such as with the doors of refrigerators and with the doors of various kinds of buildings, particularly adapted for use with the hinged doors of presentday automobiles. In such automobile doors, window panes are slidably mounted and for greater visibility, such panes are movable into close proximity with certain sections of the free side edge walls of said doors; as fully disclosed in my aforesaid Patent No. 2,094,413 for Door control mechanism. Like the door control mechanisms illustrated in such patent, the door holding and door control mechanisms here illustrated are of such character that they may be readily and conveniently associated with such door sections, without interfering in any way with the movement of the window panes within said doors.

As heretofore pointed out, the door control provided by the present invention may be (A) a latch control only, or (B) a throw-out control only, or (C) a combined latch and throw-out control. Solely for purposes of illustration, the accompanying drawings show embodiments of the present invention which provide combined latch and throw-out controls, but if desired, the mechanisms constituting such embodiments may be readily modified, in an exceedingly simple and inexpensive manner, to provide latch controls only or throw-cut controls only, as will be hereinafter explained.

Although the door control parts (and, of course, the door holding parts) of mechanisms embodying the present invention may vary or differ widely as to construction, arrangement, actuation, etc., the door control parts here shown are, generally speaking, of the same character as those disclosed in my aforesaid Patent No. 2,094,413 for Door control mechanism, to which patent reference may be had. For simplicity and convenience, only those door control parts which are necessary or desirable for a proper understanding of the present invention are here illustrated.

Referring now to that embodiment of door holding and door control mechanism illustrated in Figs. 1 to 6 inclusive, it will be noted that the door control parts of such mechanism (latch and throw-out control parts) include a door latch arm I! and a door throw-out arm I3, said arms being either separate members, or as here shown, integral parts of a generally flat bifurcated memcontrol mechanism,

ber ll of metal or other rigid material. For cooperation with said arms in the latch and throw-out control of the hinged automobile door I (which door is a standard metal door such as is now used in the automotive industry), any suitable means may be utilized, the means here shown being a simple keeper pin ll of metal or other rigid material.

As pointed out in my aforesaid Patent No. 2,094,413 for Door control mechanism and as will be readily understood, either the arms l2 and ii (the bifurcated door control member H) or the keeper pin il may be associated with the automobile door IB and the other associated with the automobile body door frame therefor. As here shown (the embodiment of Figs. 1 to 6 inclusive), the arms I2 and it are associated with asection ll of the free side edge wall (the edge wall opposite the hinged edge wall) of the door I, and the keeper pin i1 is associated with a section I! of the automobile body door frame, as in my aforesaid Patent No. 2,094,413 for Door said door section II and said door frame section I! being adjacent and in suitable alignment when the door It position, as indicated in Fig. 3.

The association of the latch and throw-out arms i2 and I3 with the wall section I! of the latch" side of the automobile door II is here eifected by the use of a relatively short stub shaft 2| which extends generally horizontally through such wall section and has oscillatory movement about its general horizontal longitudinal axis. On that end portion of said stub shaft which here lies outside the door it is rigidly mounted the bifurcated door control member ll of which the arms l2 and [3 are parts, the securement of said bifurcated member on said stub shaft being such that the arms l2 and I! are here dependently disposed relative thereto, as clearly shown in the accompanying drawings. Any suitable support for the stub shaft 2i may be utilized, and in the or any other suitable material, said element lying alongside the transverse portion 22 of the latch plate and hence being closely adjacent the door wall section I. Inasmuch as both said element and the bifurcated door control member ll are here rigidly mounted on the stub shaft 2|, oscillatory movement of the latch and throw-out arms of said bifurcated member effects corresponding movement of said element and oscillatory movement of said element effects corresponding movement of said latch and throw-out arms, the movement of said arms and said element, in this embodiment of the present invention, being in planes substantially vertical and transversely of the side walls of said door.

As heretofore pointed out, the keeper pin I1 is associated with the side edge wall section II of the automobile body door frame for the door IS, the disposition of the longitudinal axis of said keeper 'pin being substantially horizontal. The association of said keeper pin with said door frame'wall section I I is here of such character that said keeper pin is immovable in an up and down direction relative to such door frame wall section II when the door it is closed. As here shown, such an association is effected by providing said keeper pin with a rigid base plate 2 which is rigidly secured, such as by screws 21 or the like, to an anchor plate II lying bdiind said wall section ll, with the result that said keeper pin base plate and said-anchor plate are rigidly or immovably secured or clamped on opposite sides of said wall section. To permit, prior to such rigid securement thereof, limited adjustment of said keeper pin il, either horizontally or vertically, for the compensation of variations, etc., in the manufacture and/or in the mounting of the door It, the openings 29 in said door frame wall section I! for the shanks of the screws 21 are made somewhat larger than said screw shanks, as clearly shown in Fig. 3. For the convenient holding of the anchor plate 28, to

facilitate assembly of the parts, etc., a suitable.

retainer is here welded or otherwisesuitably secured to the inner surface of the door frame wall section IS, the chamber of said retainer Fig. 2, and a predetermined operated position.

shown in dotted lines, Figs. 2 and 6. The single predetermined operative position of the latch arm I! is its door-latching position, (see Fig. 4,-

for example), in which position such arm extends downwardly along the inner side of the keeper pin l1 and effectively and positively latches the automobile door It in a single predetermined closedposltion. The predetermined operated position oi the latch arm I! is its 'unlatching position, (see Fig. 6,'for example), in which position said arm extends inwardly and downwardly; with no door-latching effect upon the keeper pin il. Thesingle predetermined operative position of the throw-out arm I! is what may be termed its potential door throw-out position, aposition in which said arm extends downwardly along the outer side of the keeper pin l1 (see Fig. 4, for example) ,ready for door-- throw-out or door-opening'movement. The predetermined operated position of said throw-out arm is what may be termed its door thrown-out position, the door having been thrown out by said arm toat least partially open position and said arm being inwardly and downwardly dis- 'posed, as clearly shown in dotted lines, Figs. 2

and 6.

In mechanism embodying the present invention, whether the door control provided thereby is a latch control only or a throw-out control only or a combined latch and throw-out control, means is provided for automatically maintaining the door control arm or arms in operated position whenever the door with which such mechanism is used is-open. If the mechanism is to provide a door latch control only, such maintaining means may be of any suitable nature.

If the"mechanism is to provide a door throw-out control only or a combined door latch and door throw-out control, such maintaining means is preferably a power means of one kind or an 1 other. With mechanism providing a door ing movement (clockwise movement, Figs. 5 and tent, a suitable yieldable abutment is here prothrow-out control only,such power means may also be used to move the throw-out arm from its predetermined operative position to its predetermined operated position, to effect automatic throw-out or opening movement of the -door 5 with which such mechanism is used; and with mechanism providing'a combined door latch and door throw-out control, such as is here illustrated, such power means also may be utilized to move the latch arm from its predetermined operative position to its predetermined operated position, to effect unlatching of the doorwith which such mechanism is used and to move the throw-out arm from its predetermined operative position to its predetermined operated position,

to thereby effect automatic throw-out or opening movement of such door.

In the embodiment of the present invention as illustrated in Figs. 1 to 6 inclusive, a generally the springs 32, whichis here suitably mounted on the transverse portion 12 of the latch plate, coacts with or is eflective upon the element 24 of the shaft 2i, with the result that the latch and throw-out arms I! and II of said shaft are normally urged by said spring toward their predetermined operated position. I

As will be readily understood, the operated positon of the latch and throw-out arms I! and i8 is'controlled by the extent of the inward swin 6) of such arms, which in turn is controlled by the extent of inward movement (clockwise movement, Figs. 5 and- 6) of the shaft element 24 with which such arms turn. To yieldingly but eifectively limit inward or clockwise movement of the shalt element 24,- when the latch and throw-out arms have been swung inwardly or clockwise to thedesired and predetermined exvided for such shaft'element. As here shown, said yieldable abutment is'a metal-capped rub -ber block 3| which is suitably secured to a longitudinally disposed portion 35 of the latch plate,

said latch plate portion 35 preferably lying alongside or adjacent the inner side wall 36 of the automobile door it, as shown in Figs. 5 and 6.

When the automobile door It is open, the latch and throw-out arms i2 and iii are in their operated position (their dotted line position, Fig. 6), said arms having been moved to, and being maintained in, such operated position by the spring or power means 32. During the latter part of the closing movement of said automobile door, the throw-out arm ll strikes the keeper pin II on the automobile body door frame, and with said throw-out arm acting somewhat as a crank arm, the final movement of the door It to closed position enables said keeper pin and said crank acting" throw -out arm to bring about the movement of the latch and throw-out arms to their single predetermined operative position (their dotted line position, Fig. 5), on opposite sides of said keeper pin, (see Fig. 4), the'latch arm being then in its door-latching position and the throw- 7 out arm being then in what has heretofore been termed its door throw-out position, that is, in position to throw the door outwardly to at least partially open position upon the unlatching thereof.

In order to enable the latch and throw-out arms l2 and I! to be releasably detained in their single predetermined operative position, upon opposite sides of the keeper pin [1, upon the closing of the door It, notwithstanding the normal tendency of the power spring 32 to move said arms toward their operated position, mechanism embodying the present invention includes suitable detent means for such purpose. Inthe embodiment of the invention illustrated in Figs. 1 to 6 inclusive, the detent means is a generally flat plate-like member of metal or other suitable material, said detent member being pivotally mounted by the use of a suitable pin 4| on the transverse portion 22 of the latch plate and being located Just above the shaft element 24 with which said detent member cooperates in the releasable detention of the latch and throw-out arms in their single predetermined operative position when the door i6 is in closed position.

Although the detent member 40 and the shaft element 24 may be provided with cooperating abutments of any suitable'form and location, for the releasable detention of the latch and throwout arms in their single predetermined operative position when the automobile door is in closed position, such detent member and such shaft element are here provided with cooperating edge abutments or shoulders 44 and 45, respectively. As will be readily understood, any suitable means may be utilized to effect detaining cooperation or engagement of such shoulders 44 and upon the movement of the latch and throw-out arms to their single predetermined operative position. For example, the weight of the detent member 40 may be so distributed that said member has a normal gravitational tendency to turn in a counter-clockwise direction (Figs. 5 and 6) to effect detaining cooperation or engagement of its shoulder 44 with the shaft element shoulder 45 upon the closing of the door l6 or, if desired, spring means may be utilized, either with or without gravitational aid, to bring about such a tendency on the part of the detent member 40 to move in'such a counter-clockwise direction. To insure detaining cooperation or engagement of the shoulders 44 and 45 of the detent member 40 and the shaft element 24, whenever the latch and throw-out arms I2 and II are moved to their predetermined operative position, not only is the weight of said detent member so distributed that said member has a normal gravitational tendency to turn in a counter-clockwise direction (Figs. 5 and 6) but also, suitable spring means 4! is utilized to cause said detent member to normally tend to turn in such counter-clockwise direction. As here shown, the spring means 48 is a simple wire spring having its intermediate portion coiled about the pivot pin 4| for the detent member 40 and having its end portions anchored to or otherwise suitably associated with said detent member and the transverse portion 22 of the latch plate.

In the use of mechanisms embodying the present invention with the doors of certain structures, such as with the doors of refrigerators, for example, it will probably be sufficient to provide such mechanism with a single manually operable means for the actuation of the detent means of such mechanism to effect the release of the door anaau control arm or arms thereof. In the use of mechanism embodying the present invention with the door of an automobile, however, two manually operable means for such releasing actuation of the detent means preferably should be provided, namely, an outside manually operable means and an inside manually operable means, so that either a person outside or a person inside said automobile can conveniently effect the unlatching of the automobile door with which such mechanism is used, or the outward throwing of such door to at least partially open position, or both. Although the accompanying drawings show door holding and door control mechanisms as used with an automobile door, the particular character of the means, or the number of such means, for effecting releasing actuation of the detent member 48 form no part of the present invention, and in the accompanying drawings, therefore, a single outside means is illustrated for effecting such actuation of the detent member 40. In my prior Patent No. 2,094,413 for Door control mechanism, however, two manually operable means (one an outside means and the other an inside means) are dis closed for selectively effecting releasing actuation of a detent member of the character of the one here illustrated, and reference to that patent may be had, if desired, for a disclosure of an inside manually operable means for effecting such actuation of the detent member 40 here shown.

The single outside means here illustrated for effecting releasing actuation of said detent member 40 is a simple push button 50 suitably mounted, adjacent said detent member, in the outer side wall SI of the automobile door l6, said push button being adapted, when manually depressed, to have direct operative engagement with said detent. member for the actuation thereof. Inasmuch as said push button engages or contacts with said detent member below the pin 4|, about which said detent member pivots or swings, manual depression of said push button directly effects clockwise movement (Figs. 5 and 6) of said detent member, with the consequent release of the shaft element 24 and the consequent movement of the latch and throw-out arms l2 and II! to their predetermined operated position, all as willl be readily understood.

The general operation of the door control parts of the present door holding and door control mechanism, as exemplified by the embodiment of the invention illustrated in Figs. 1 to 6 inclusive, is as follows:

When the door It is in closed position, the latch and throw-out arms l2 and II are in their single predetermined operative position on opposite sides of the keeper pin ll (as in Fig. 4), the latch arm l2 being inlatching position, with the consequent latching of the door in its single predetermined closed position, and the throw-out arm It being in throw-out position, that is, in position to effect the automatic throwing of such door to at least partially open position upon the unlatching thereof. The releasable detention in their single predetermined operative position of the latch and throw-out arms, when the door it is in closed position, is effected by the detent member 40, the shoulder 44 of which has releasable detaining cooperation or engagement at such times with the shoulder 45 of the shaft element 24. As the detent member 40 has a normal tendency to move in a counter-clockwise direction, Figs. 5 and 6, under the influence of gravity and its spring 48, and as the shaft element 24 has a When it is desired to unlatch said door and automatically eifect the throwing of said door to s at .least partially open position, releasing actuation (clockwise movement, Figs. and 6) of the detent member 40 is manually effected, such as by manual depression of the push button 50in the embodiment of the invention illustratedin j Figs. 1 tom inclusive. Upon completion oisuchj releasing actuation (clockwise movement, Figs. 5' and 6) ofthe detent member 40,1inison clockwise movement of the shaft element 24, the shaft 2| and the arms I2 and i3 automatically results, said arms moving from their single predetermined operative position, Fig. 5, to their predetermined operated position, Fig. 6. As the operated position of said latch arm is its unlatching position, the movement of said latch arm to such operated or unlatching position effects, of course, the unlatching of the door IE, and as the operated position of said throw-out arm is its door thrownout phsition, the movement of such throw-out arm to its operated or thrown-out position efiects, of course, the throwing of said door to at least partially open position. Due in large part to the character of the cooperating shoulders 44 and 45 oi. the detent member Ml and the shaft element lit (said shoulders 44 and 45 preferably being either the chord or the arc of a circle of which the detent member pivot pin M is-the center) (see, for example, Fig. 26 of the drawings, and the latter part of the first column of page 6 of the specification of my aforesaid Patent No. 2,094,413 for Door control mechanism), clockwise releasing actuation of the detent member 40 is easily effected,the amount of pressure required for the depression of the push button 50 being extremely small.

When the automobile door it is open, the latch and throw-out arms l2 and i3 are in their operated position, as shown in dotted lines, Figs. 2 and 6, the operated position of the latch arm being its unlatching position and the operated position of the throw-out arm being its door thrown-out position. As heretofore pointed out, upon the closing of said door, the door throw-out arm I3 strikes the keeper, pin ii on the automobile body door frame, and! continued closing movement or said door results in the movement of said latch and throw-out arms to their single predetermined operative position, on opposite sides of said keeper pin, the throw-out arm in such cooperation with said keeper pin acting as a crank arm, as will be readily understood. Upon the closing of the door, therefore, the latch arm it is moved to its single predetermined operative or latching position, with the consequent latching of the door in a single predetermined closed position, and the throw-out arm i3 is moved to its single predetermined operative or door throwout position; ready for. automatic door throw-out movement when the door is next unlatched. Inasmuch as the shaft element 24 moves in unison With the latch and throw-out arms, the closing of the door i also moves said shaft element into cooperative relationship with the detent member till, the shoulders M and id of said detent member and said shaft element being thus brought into releasable detaining cooperation or engagement. Upon the closing of the door l6, therefore, the detent member 40 becomes effective to releasably detain, when the door is in closed post-- tion, the'latch and throw-out arms in their single predetermined operative position. As will also be understood, the closing of the door It also results in the loading of the power spring 32,

inasmuch as the upper end portion of said spring is moved to loaded! position by the shaft element 2t upon the closing of said door.

.As clearly shown in the accompanying draw- ;ings (see Figs. 2 and 4), the throw-out arm it preferably'has a suitable cam 54 on the inner edge of its free end portion, not only for cooperative engagement with the keeper pin il in the movementof th'elatch and throw-out arms l2 and l3 to'their operative position upon the closing of the door [6 but also, for cooperation with such keeper pin in the throwing of such door to at least partially open position upon the unlatching of said door. As will also be noted from an examination of the accompanying drawings, the

free end of the throw-out arm i3 is disposed beyond the free end portion of the latch arm it, or in other words, the distance between the free end of the throw-out arm and the longitudinab axis of the shaft 2!, about which the latch and throw-out arms swing or pivot, is somewhat greater than the distance between the free end of the latch arm I2 and. such shaft axis. One of the advantages of such a construction is that the movement of the latch and throw-out arms to their single predetermined operative position, and the consequent latching of the door it in its single predetermined closed position, can be more easily and more emciently eifected, and another of the advantages thereof is that the outward throwing movement of such door can. be more easily and more emciently effected, with the door being thrown open to a somewhat greater extent, say to six inches or so. As to such first-mentioned advantage, it may be pointed out (a) that the inward swingingmovement (clockwise movement, Figs. 2 and 6) of the latch and throw-put arms need not be of such extent as to horizontally dispose'said arms for an operated position thereof, the present latch and throw-out arms when in their predetermined operated position (their dotted line position, Figs.

2 and 6) being angularly disposed, and (b) that the latch arm I2, in moving from its predeterruined operated position to its single predetermined operative position, clears the keeper pin it and does not actually engage such pin until such arm is in substantially its operative posi tion.

As heretofore pointed out, mechanism embodying the present invention not only effects the control of a hinged door, such as the latch and throw-out control of the automobile door it; as

just described, but also effects, when said door is in closed position, the more or less rigid or unyieldable holding of the latch side of such door against movement in the general direction of its hinge axis (in an up and down direction in the case of the automobile door It here shown).

As clearly shown in Figs. 3 and 4 of the accompanying drawings in connection with the embodiment of the invention illustrated in Figs. 1

to 6 inclusive, the bifurcated door control mamher it rests or seats upon the rigid keeper pin I! when the automobile door it is in closed position, said keeper pin being located at such times at the inner and upper end of the slot or recess Wit lit of said bifurcated member. Inasmuch as said lceeper pin is here rigidly mounted on the automobile body door frame, and hence is immovable in an up and down direction relative to such automobile body door frame, and inasmuch as the rigid bifurcated door control member I4 is immovable in an up and down direction relative to the automobile door i8 when such door is in closed position, the seating engagement of said bifurcated door control member on said keeper pin effects the rigid or unyieldable holding of the latch side of said door against downward door control member l4.

movement when said door is its closed position, as will be readily underst For rigidly holding the latch side of the automobile door l6 against upward movement relative to the surrounding frame therefor when said door is in its closed position, the door holding and door control mechanism of Figs. 1 to 6 inclusive includes a horizontally disposed takeup member or wedge 60 and a suitable retainer therefor, said take-up member or wedge, as here shown, being of metal or other rigid material and being slidably mounted within its retainer for door-holding cooperation with the bifurcated In this particular embodiment of the invention, the take-up member or wedge 60 and its retainer are transversely associated with the wall section IS of the automobile body door frame for the door l6, said take-up member or wedge being located a sufficient distance above keeper pin i'l on said wall section to permit the bifurcated door control member ll, associated with the door 16, to be rigidly wedged therebetween for d00r-h01dlng purposes when said door is in its closed position.

As here shown, theretainer for the take-up member or wedge 60 comprises two rigid retainer plates 6! and 62, upper and overlapping portions of which are rigidly secured, such as by the screw 63, to the anchor plate 28 heretofore referred to and which is located behind the wall section IQ of the automobile body door frame. Overlapping and angularly disposed intermediate portions 64 and B5 of said retainer plates provide at all times a rigid onunyieldable upper abutmerit for the take-up member or wedge 60, said take-up member or wedge being arranged for endwise slidable movement in the chamber formed by the spaced lower end portions 61 and 88 of said retainer plates. For the purpose of enabling said take-up member or wedge to be retained within such chamber, a longitudinally disposed and transversely extending groove I0 is here provided in a side wall of said take-up member or wedge, and into such groove extends a ,correspondingly disposed transverse edge flange ll of the retainer plate portion 61. To limit the slidable movement of the take-up member or wedge within the chamber of its retainer, (the movement of said take-up member or wedge being transversely of the longitudinal axis of the stub shaft 2| on which is rigidly mounted the bifurcated door control member I! and the shaft element 24), the ends of said chamber are here closed by portions 13 and H of one of said retainer plates, and to normally urge said take-up member or wedge outwardly for wedging cooperation with the bifurcated door control member H when the door 46 is closed, a helical compression spring 16 is here interposed between said take-up member or wedge and the end wall 14 of the retainer chamber therefor. If desired and as here shown, the inner end portion of said take-up member or wedge may be provided with a suitable socket 18 for the reception of the outer end portion of the helical compression spring 16 and the chamber end wall H may be provided with a centering projection 19 for the inner end of said spring, the effect of said socket and said centering projection being to maintain the spring 16 in horizontal alignment at all.times with the longitudinal axis of the take-up member or wedge 80, as will be readily understood.

Upon the closing of the automobile door IS, the bifurcated door control member ll associated with said door moves beneath the takeup member or wedge 60, the top surface 8| of said bifurcated member and the bottom surface 82 of said take-up member or wedge being thus brought into cooperative door holding engagement. As here shown, the bottom contact surface 82 of said take-up member or wedge is downwardly and inwardly inclined from its outer end, and the top contact surface 8! of the bifurcated door control member l4, when such surface is in cooperative engagement with the bottom surface 82 of said take-up member or wedge, has a corresponding inclination, the effect of which is to insure proper cooperative engagement of said contact surfaces upon the movement of the door I6 to closed position. As clearly shown in Fig. 4, however, the angle of inclination of the contact surfaces 8| and 82, when said surfaces are in cooperative engagement, is only about twelve degrees to the horizontal, or in other words, to the generally horizontal path of movement of the take-up member or wedge 60, so that the inclination of such contact surfaces is what may be termed a locking inclination and hence is one that does not prevent cooperative engagement thereof from effecting the desired rigid holding of the latch side of the door I6 against upward movement when said door is in its closed position.

Because of the normal tendency of the takeup member or wedge 60 to move outwardly, under the influence of its compression spring Hi, the rigid bifurcated door control member I4 is rigidly or unyieldably positioned and wedged, upon the movement of the door IE to closed position, between the rigid keeper pin l1 and the rigid take-up member or wedge 60, and inasmuch as said keeper pin and said take-up member or wedge are immovable in an up anddown direction (the general direction of the hinge axis of the door [6) relative to the automobile body door frame with which they are here associated, the latch side of the automobile door 16 is, as a. consequence, rigidly or unyieldably held against up and down movement when in its closed position within said body door frame.

As will be readily understood, the compression spring 16 for the take-up member or wedge 60 also performs the function of effectively taking up any variation caused by wear, misalignment, etc., the range of slidable movement of said take-up member or wedge within the chamber of its retainer being sufficiently great for such purpose. As a. result, when mechanism embodying the present invention is once installed, no further attention to it is necessary.-

In the door holding and door control mechanism constituting the embodiment of the present invention illustrated in Figs. 7 and 8, a modifled form of rigid take-up member is utilized for door-holding cooperation with the bifurcated door control member of such mechanism. As shown, the take-up member 85 of the mechanism of Figs. 7 and 8 is a pivotally, rather than base plate 26a of the rigid keeper pin I'Ia is here provided, above said keeper pin, with a rigid pin 86 on which said take-up member pivots, said take-up member being dependingly disposed relative to its pivot pin, Like the slidable take-up member or wedge 60 of the mechanism of Figs. 1 to 6 inclusive, the pivoted takeup member 85 of the mechanism'of Figs. 7 and 8 is provided with suitable means, such as a spring 88, for normally urging it outwardly. Moreover, the take-up member 85 has its weight so distributed relative to its pivot pin 86 that such member has a normal gravitational tendency to swing outwardly, as will be readily apparent from an examination of Fig. 8. As here shown, the spring 88 is a simple wire spring, the intermediate portion of which is coiled about the pivot pin 86 for the take-up member 85 and the end portions of said spring are suitably anchored to said take-up member and to the keeper-pin base plate 26a. For limiting the outward swinging movement of the take-up member 85, under the influence of its spring 88, a

up member upon the movement of the hinged door Ilia to its single predetermined closed position, said bifurcated door control member being seated at such times upon said keeper pin and said pivoted take-up member being immovable in an up and down direction relative to the door frame on which it is pivoted when the door l6a is in its closed position. As a result, the latch side of the hinged door lGa, like that of the door I6, is rigidly or unyieldabiy held against up and down movement whenever it is in closed position, all as will be readily understood.

As clearly shown in Fig. 4, the bifurcated door control member ll of the mechanism illustrated in Figs. 1 to 6 inclusive has an arcuately shaped contact surface 92 at the inner and upper end of its slot or recess 58 for seating engagement upon the correspondingly shaped top surface of the keeper pin l1 when the door I6 is in closed position. In the embodiment of the invention illustrated in Figs. 7 and 8, however, the bifurcated door control member Ma is so shaped that two laterally spaced or separated contact or bearing surfaces 93 are provided at the inner and upper end of its slot or recess 58a for seating engagement upon the arcuately shaped top surface of the keeper pin l'la when the door l6a is in closed position. As shown in Fig. 8, such laterally spaced contact surfaces 93 are here disposed at substantially right angles to each other, (although the angular relationship of such contact surfaces obviously may be varied, as desired), with the result that when the door l6a is in its closed position, inward and outward movement of the bifurcated door control member Ho, and hence of said door, is effectively prevented. By the use of a door control member of the character illustrated in Figs. 7 and 8, therefore, as well as by the use of a door control member of the character illustrated in Figs. 1 to 6 inclusive,

door bumpers are not needed to insure for a door a single predetermined closed position, and the use of such door bumpers with the here illustrated embodiments of the present invention may be dispensed with. It is to be understood, of course, that the pivoted door control member I! of the mechanism of Figs. 1 to 6 inclusive, and the pivoted door control members of the hereinafter described mechanisms of Figs. 9 and 10, and of Figs. 13 and 14, may be provided, if desired, with opposed contact surfaces of the general character as those illustrated in Figs, 7 and 8,

rather than with arcuately shaped contact surfaces, as here shown.

In the mechanism of Figs. 1 to 6 inclusive and in the mechanism of Figs. 7 and 8, the pivoted door control means (the bifurcated member M of Figs. 1 to 6 inclusive and the bifurcated member Ila of Figs. 7 and 8) have cooperative contact or engagement with movable take-up members (the slidable take-up member or wedge 60 of Figs. 1 to 6 inclusive and the pivoted take-up member 85 of Figs. '7 and 8) for rigidly or onyieldably holding a' door against upward movement. If desired, however, the pivoted door control means of mechanism embodying the present invention may have cooperative contact or engagement, for such door-holding purposes, with a stationary or rigidly mounted holding member, and three embodiments of mechanism of such character are here illustrated, one such embodiment being illustrated in Figs. 9 and 10, another in Figs. 11 and 12, and still another in Figs. 13 and 14.

In the embodiment of the invention illustrated in Figs. 9 and 10, the pivotally mounted bifurcated door control member b has cooperative contact or engagement, for door-holding purposes, with a relatively flat plate-like holding member 95 which is rigidly associated in any suitable manner with that structure (either a door structure or the body frame structure therefor) with which is associated the keeper pin llb. For example, said holding member 95 may be an integral part of the keeper pin base plate 261), as here indicated, or it may be a separate member rigidly secured to such base plate in any suitable manner. As indicated in Figs. 9 and 10, the arcuately shaped top surface 96 of the door control member b is adapted for cooperative contact or engagement, for door holding purposes, with the correspondingly shaped bottom surface 91 of the rigidly mounted holding member 95,

'said holding'member bottom surface and the top surface of the keeper pin llb being spaced or separated sufficiently to permit said door control .member b to be wedged therebetween upon the movement of said door control member to its single predetermined operative position, (or in other words, upon the movement to its single predetermined closed position of the door with which this mechanism is used). Ashere shown, the arcuately shaped top contact surface 96 of the door control member MD is eccentrically related to the longitudinal axis of the stub shaft 2lb about which such door control member swings, said top contact surface 96 being the arc of a circle of which the center is indicated at 98, (see Fig. 9) said center being located outwardly from the longitudinal axis of the stub shaft lib.

As will be readily understood, upon the closing of the door with which is used the mechanism of Figs. 9 and 10, the door control member Mb will be swung from its predetermined operated position, shown in Fig. 10, to its single predetermined operative position, shown in Fig. 9, the longitudinal axis of the stub shaft 2Ib having substantially horizontal movement. The are center 98 of the door control member Ilb, however,

gradually rises during the movement of said member from its operated position to its operative position, with a corresponding rise, of course,

of the top contact surface of said member,

the door with which such mechanism is used is insured. Moreover, as the angular relationship of the cooperative contact surfaces 96, 91 of the door control member band the rigidly mounted holding member are of locking" character, the rigid or unyieldable holding of the latch side of such door against upward movement relative to its surrounding frame likewise is insured, all as will be readily understood.

In the embodiment of the invention illustrated in Figs. 11 and 12, the latch side of the door with which such mechanism is used is rigidly or unyieldably held against upward movement by the cooperative contact or engagement of the generally horizontal bottom surface I02 of the rigidly mounted holding member I03 and the arcuately shaped top surface I04 of the pivotally mounted bifurcated door control member Ilc, such top contact surface of said door control member being concentrically related to the stub shaft axis about which such member swings. In this embodiment of the invention, a take-up member is associated with the keeper pin He, the take-up member here shown comprising a relatively short arm I00 and a depending extension I01, the lower end portion of said take-up member arm being pivotally mounted upon said keeper pin. When the door with which this mechanism is used is in open position, the takeup member of such mechanism occupies the position shown in Fig. 12, the depending extension I01 of said member being held against a stop pin I08 or the like by spring or other suitable means IIO.

Upon the movement to closed position of the door with which this mechanism is used, the arm I06 of the take-up member of such mechanism is engaged by the throw-out arm of the bifurcated door control member Ilc, as indicated in Fig, 12, and during the movement of said door control member from its predetermined operated position to its single predetermined operative position, said take-up member is swung from its Fig. 12 position to its Fig. 11 position, the latter position of said take-up member being its door holding position, as will be readily understood. When said take-up member is in its door holding position, the arm I06 thereof is engaged by the bifurcated door control member Ilc at two laterally spaced places, one on the outer side of the axis of the keeper pin Ho and the other on the inner side thereof, as clearly shown in Fig. 11. Inasmuch as the cooperating outer contact surfaces of said door control member 140 and said take-up member arm I06 are of locking character, the seating engagement of said door control member upon said take-up member arm effectively prevents, in a rigid or unyieldable manner, any downward movement of the latch side of the door with which this mechanism is used. Moreover, as the door control member I40 is wedged between said take-up member arm I08 (said take-up member when in its door holding position, Fig. 11, being immovable in an up and down direction) and the rigidly mounted holding member I03 when said door is in closed position, the latch side of such door is rigidly or unyieldably held against upward movement relative to its surrounding frame. With this mechanism, any wear which occurs will be readily taken up, as the pivoted door control member Ilc. upon moving from its operated position to its operative position during door-closing movement, always moves the arm I06 of the take-up member of such mechanism to a position wherein such arm and said door control member contact or inter-engage for door-holding purposes, all as will be readily understood.

In the embodiment of the invention illustrated in Figs. 13 and 14, a take-up member H5 is pivotally mounted, by means of a pin II6, upon the upper end portion of the pivotally mounted bifurcated door control member lid, for cooperative contact or engagement with the rigidly mounted holding member II! in effecting rigid or unyieldable holding against upward movement of the latch side of the door with which this mechanism is used. As shown, the arcuately shaped top surface II 8 of said take-up member is located above the top surface of said door control member for door holding contact or engagement with the generally horizontal bottom surface III! of the holding member I I1, and inasmuch as such cooperative surfaces IIB, I I9 are of "locking" character, there is no liability of undesired lateral movement of said take-up member when such member is cooperatively related to said holding member for door holding purposes. Due to the eccentric relationship of the arcuately shaped top surface II8 of said take-up member relative to the axis of its pivot pin IIS, the areas of contact of the surfaces H8, H9 are outwardly disposed, as clearly shown in Fig. 13, relative to the center line of the pivot pin I I6 and the stub shaft 2Icl about which swing, respectively, the take-up member H5 and the door control member Md. As a result, no jamming of the parts is possible upon the opening of the door with which this mechanism is used. As with the pivoted take-up member 85 of the mechanism of Figs. 7 and 8, the take-up member H5 of this mechanism has provided therefor a stop pin I22 or the like and spring or other means I23 for normally urging said take-up member toward said stop pin or in a counter-clockwise direction, Figs. 13 and 14. Like the take-up spring 80 of the mechanism of Figs. 7 and 8, the take-up spring I23 of this mechanism automatically takes up or compensates for wear of the parts, etc.

From the foregoing description of several forms of mechanism embodying the present invention, it will be readily apparent that cash of such mechanisms effects, in a particularly practical and efllcient manner, the control of a hinged door and the rigid or unyieldable holding of the latch side of such door against movement in the general direction of its hinge axis (in an up and down direction in the case of the doors here shown). If mechanism embodying the present invention is used with a door which swings about a horizontal axis, then such mechanism will effect the more or less rigid or unyieldable holding of the flatch side of such door against movement in a side to side or horizontal direction, the direction of the hinge axis of such door, all as will be readily understood.

Although each of the mechanisms here illustrated is adapted to rigidly or unyieldably hold the flatch side of a door against movement in the general direction of its hinge axis, some movement of the latch side of a door in the general direction of its hinge axis may be permitted, if desired, and it is quite obvious how each of the mechanisms'here illustrated might be modified, in an exceedingly simple and inexpensive manner, to permit limited movement of the latch side of each of the doors here shown in-the general direction of its hinge axis. For example, in the mechanism illustrated in Figs. 1 to 6 inclusive, limited movement of the latch" side of the door IS, in the general direction of the hinge axis of such door, may be effected, if desired, by so mounting the slidable take-up member or wedge and the keeper pin 11 that either or both thereof have limited move ment in the general direction of the hinge axis of such door. In an equally simple and obvious manner, each of the other mechanisms 'here'illustrated may be modified to permit limited or more or less movement, in the general direction of its hinge axis, of the latch side of the door with which such mechanism is used.

The present invention, therefore, covers and includes door holding and "door control mecha-.

nism by means of which a hinge door is controlled and by means of which the latch side of said door, when said door is in its closed position, is held against all movement, or is permitted, to have, limited movement only, in. the

general direction of the hinge axis of such door. In the appended claims, the term or expression "substantially immovable" is to be understood and construed as covering or including not'only total immovability but also, movability to.a'lim-' ited amount or degree.

It is not necessary, of course, thatthe keeper pins here shown be immovably or rigidly mounted, it being sufficient if such pins are immovableor substantially immovable, in the general directions of thehinge axes of the doors with which they are used, when such doors are in their closed positions. Obviously, said keeper pins could be mounted for rotary movement about specification of such patent), or anti-friction sleeves could be rotatably mounted on such keeper pins, all as will be readily understood.

In the here illustrated embodiments of the present invention, the-bifurcated door control members (l4, Ila, etc.) not only cooperate with the keeper pins (l1, Ila, etc.) for door control purposes but also, seat thereon for door holding purposes.- It is to be understood, however, that such bifurcated door control members and such keeper pins may be reversed or inverted as to their relative positions, so as to locate such keeper pins for seating engagement upon said bifurcated door control members, for door holding purposes,

when the doors with which such mechanisms are been here shown for purposes of illustration and not of limitation. To enable any of thedoor holding and door control mechanisms here illustrated to provide a door throw-out control only, it is merely necessary to remove from the pivoted door control member of such mechanismthe latch arm thereof, which may be easily and quickly accomplished, and to provide for the door with which such mechanism is used any suitable latch means or the like for releasably retaining .said door in closed position. The door control provided by such mechanism'will then be a door throw-out control'only. To enable any of the door holding and door control mechanisms here illustrated to provide a door latch control only,

it is merely necessary to substitute in such mechanism for the spring or power means 32 (shown only in connection with the embodiment of the invention illustrated in Figs. 1 to 6 inclusive) 8 spring or the like with .insuflicient force to eflfect door throw-out movement. such a "light spring or the like will than merely be the automatic maintenance of the latch and cra'nk arms of such mechanism in operated position when the door with which such mechanismis'used is in open position, all aswill be readily understood.

Further objects and advantages of the present invention will be obvious'to thoseskilled in the art to which it relates.
